"What I don't want is to be loaned out," said Lukaku, according to the The Mirror. "I am 21 and I have been loaned for the last two seasons. Thibaut Courtois was loaned for three seasons and will be without doubt the first-choice Chelsea goalkeeper.

"And Kevin De Bruyne has been transferred permanently to Wolfsburg. They are free in their heads - it is not my case. That would free me totally."

He scored Belgium's extra-time winner against the USA in the last 16 of the World Cup and has been linked with Juventus and Monaco along with Atletico Madrid - where he could prove a direct replacement for Costa.

Indeed, reports in Spain claim that Atletico have already reached a deal with Chelsea for the striker - who is determined to play in the Champions League next season in order to further his development.

"I don't know - there are several clubs that are interested," he said. "I need to make a good decision to reach the absolute top. It is a dream for every attacker. I want to show what I can do and play in the Champions League with a big club.

"The decision will soon be taken. I have some ideas but we will have to see what is best for the clubs. I don't want to negotiate before the clubs have come to an agreement."
